Definitions

  • the invention relates to an outer hook spool with a cylindrical coil core, which contains a core opening, on which hooks are formed, and which is preferably provided with two flange washers, for the winding of band-shaped elastic materials, in particular film materials, which in turn for hooking into the coil hooks accordingly shaped hook holes are provided.
  • a large number of reel designs are known which are used to wind up various types of tape materials. These reels have the film tape attached to the reels for winding in a variety of ways, e.g. by looping, gluing, riveting, clamping or hooking on or in a slot in the coil core.
  • the object of the invention is concerned with hook spools into which the film tape provided with holes is hooked.
  • Coils are known for 35 mm films, e.g. are referred to as double hook coils. These coils have a core opening in the coil core, in which molded catch hooks and separate guide surfaces or holding bodies are brought. The end of the film with a hole is inserted into this core opening, the guide surfaces on both sides of the hooks arching the film around the hook until the hole in the film snaps into the hook. The guide surfaces prevent the film tape from automatically unhooking from the spool after the hole snaps into the hook via the film stiffness.
  • This coil form known from the document BE-A 566676 has the disadvantage that, during the automatic hooking-in process, the coil is brought into a specific position and must remain here until the hooking-in process is complete. Of course, this takes time and therefore stands in the way of even more economical use.
  • a further disadvantage of these reels is that only relatively low tensile forces can be transmitted in the case of film tape materials, which in many cases has the consequence that the film pulls out of the reel and is therefore unusable.
  • US Pat. No. 3,361,380 describes a combination of coil and film tape in which two hooks are made in a coil slot and two holes are made in the film tape to improve the holding force.
  • This spool is also only of limited suitability for securely attaching the film to the spool and does not allow it to be rotated.
  • the DT-OS 2444106 describes a spool with an outer hook, which should hook the film in rotation and secure against unhooking on both sides of the hook via guide surfaces.
  • This spool shows an unsafe hooking and therefore leads to high rejects when used in the production of film cartridges with spools.
  • the guiding surfaces provided as unhooking devices do not adequately prevent the film from unhooking from the spool.
  • the transferable tensile forces are similar to those of normal hook spools and are not satisfactory.
  • the invention has for its object to find a spool that enables rational rotary hooking of the film into the spool, guarantees a good secure holding force and, after hooking, also allows winding against the normal winding direction with secure hooking and good holding strength.
  • the formation of the catch hook with a molded counter hook pointing in the direction of the coil core axis surprisingly shows a secure connection when the hook has caught the film hole, which can also take place when the coil rotates.
  • the catch hook root and the holding body roots serve together to transmit the tensile forces between the tape and the reel.
  • a further embodiment of the invention is that the height and the mutual distance between the holding body pairs arranged next to or between the catch hooks are selected such that a correct slipping of the end of the band-shaped material into the slot is ensured.
  • a further improvement is achieved in that the guide surfaces are higher than the bottom tip of the counter-hook on the catch hook pointing in the direction of the core axis.
  • the special design of the coil core with opening, catch hook, counter hook and holding body fulfills the task and has considerable advantages over the known coils.
  • the catch hook which is released accordingly, allows the film strip fed to it to be securely hooked in rotation.
  • the rotational movement of the spool during the hooking process can take place at the same speed as the specified winding speed.
  • the holding body on the hook wall of the reel core is located at the same distance from the reel axis as the catch hook.
  • the tensile forces that can be transmitted with this combination of catch hook / holding body are considerably higher than those of the known coils.
  • Another advantage of the new spool is the release hook formed by counter hooks and at least one further holding body. With this special arrangement it is possible to transmit approximately the same tensile forces in the opposite winding direction as in the "normal" winding direction.
  • the coil shown has a coil core 1 with a core opening 2, on which the catch hook 10 with counter hook 5 and, for example, two holding bodies 3 and 9 are arranged.
  • the catch hook 10 is designed so that it exactly follows the curvature of the coil core with its outer surface.
  • a holding body 9 is arranged on the same wall of the coil core, but has only a certain height. This height is such that the free space between the holding bodies 3 and 9 allows the film to slide in under the guiding surfaces 4 and 6 which serve to prevent unhooking.
  • the film 12 is fed to the spool core so that the catch hook 10, the lower one of which is at a greater distance from the coil axis than the guide surface 6, can engage in a hole 11 in the film 12 and the film lies on the shoulder 7 of the catch hook wall. Shortly before the film 12 is placed on the shoulder 7, the second film hole 11 lies over the holding body 9 and thus increases the holding force of the catch hook 10 to approximately the double value. If the film 12 has reached its final position on the shoulder 7, the end of the film has jumped under the guide surfaces 4 and 6 and thus prevents the film 12 from automatically unhooking from the spool 1.
  • Catch hooks 10 and holding bodies 3, 9 are therefore formed in such a way that they remain within the contour of the winding surfaces of the bobbin axis remaining on the flange disks and these carry the wound film.
